Development of a multibottle gas‐tight fluid sampler WHATS II for Japanese submersibles/ROVs

This paper summarizes the design and performance of our recently developed gas‐tight fluid sampler WHATS II, especially designed to collect seafloor venting gas‐rich fluid from submersibles/remotely operated vehicles (ROVs). It consists of four 150‐cm³ stainless steel sample cylinders, eight ball valves, a motor‐driven arm, a rail, a peristaltic pump, a control unit, and a flexible Teflon tube connected to a titanium inlet tube. All the parts have been designed to be used at undersea as deep as 4000 m. The motor‐driven arm on the rail can open and close each of the four cylinders. By pumping out distilled water that has filled an open cylinder and the dead spaces of the sampler, we can fill the cylinder with sample fluid. WHATS II can take a maximum of four different gas‐tight samples in a series. The whole operation can be arranged from the cabin, etc., of a submersible/ROV. Use of only one motor to operate eight valves makes the sampler small, light (21 kg in sea water), and easy to handle. In addition, the sampler is able to collect an almost uncontaminated gas‐tight sample from the seafloor. To date, the sampler has been used in more than 90 dive surveys by Japanese submersibles/ROVs, including Shinkai 2000, Shinkai 6500, and Hyper Dolphin, with a success rate of >90%.     

The Impact of Small-Scale Development Projects on Archaeological Heritage in Africa: The Tanzanian Experience

The governments in Africa implement various development projects to improve livelihoods. The projects are both large and small scale. Large-scale projects include construction of dams, railway lines, roads, industrial complexes, expanding cities and new mines. Small-scale ones include establishing new residential houses and maintenance of roads linking administrative divisions. Both large- and small-scale projects involve land disturbance and have the potential to destroy archaeological heritage particularly when not accompanied by salvage studies. Unfortunately, archaeological salvage studies largely focus on large-scale projects. Only a handful of studies may have investigated the impact of small-scale projects. This paper focuses on small-scale projects and investigates the seven-hectare archaeological site of Bweni in NE Tanzania. The project to build fishing ponds on an area of only 350 m² destroyed archaeological heritage including human remains and ceramics of the early Swahili period, ceramics and beads of the Swahili ‘golden age’ period, and archaeological records of the post-Swahili period.     

State Archaeology and the Private Museum: An Integrated Approach to Archaeological Site Management for Local People in China

During the emergence of Chinese archaeology, the legislative system of cultural heritage in China included archaeological excavations and investigations as being the ‘exclusive right of state’. This mode of state archaeology has proved its worth by increasing the authority and quality of archaeological research and excavations, as well as enhancing the social values and benefits at the state level. The local communities, however, have hardly been embedded into the archaeological projects, nor have the archaeological projects been employed to improve local and regional economic development. This paper considers private museums as embodying regional values and beneficial to projects under the mode of state archaeology. With a case study outlining collaborations between archaeologists and local agents under the excavation and conservation of ancient kiln sites at the town of Zichuan, I argue that private museums could be relatively prominent platforms for public engagement in activities of state archaeology. It might contribute to a reconsideration of the following: indirect archaeological concerns, local economic benefits, identities and alternative interpretations of locality.     

The Shipwrecks of Xlendi Bay,Gozo, Malta

Xlendi Bay, Gozo, Malta, is a rich underwater site. It was discovered in 1961 by British Navy divers on a training mission. Since then, a significant number of artefacts has been retrieved but not well studied. This paper summarizes a recent detailed study of the archaeological material and describes five amphora types that have not yet been identified. It also takes deep‐water surveys that have recently been conducted by various teams into consideration.     

Relax,Don’t Do It: A Future for Archaeological Monitoring

Preservation in situ and the monitoring of archaeological sites have become important themes since the acceptance and implementation of the Valletta Treaty. In the last few decades, our knowledge of degradation processes has increased manyfold, and a range of techniques have been tested and applied for use in both assessment and monitoring. Despite these successes, all is not well. First, we have little notion of the speed of the decay processes involved. This makes it difficult to distinguish between acute and protracted degradation. Apart from that, many assessments and subsequent monitoring projects rely (too?) heavily on complex and costly specialist technology. For any future preservation — in situ — projects low-tech observations together with best estimates of decay rates and archaeological site information should be combined to make an accurate assessment of the effects of decay on the archaeological record. Monitoring for preservation purposes is only appropriate if (1) decay processes occur within a relevant and measurable time scale, and (2) if mitigating actions can be taken or preservation ex situ can be performed (i.e. a rescue excavation) if significant degradation takes place.     

Evaluating Community Archaeology in the UK

Abstract

Does community archaeology work? In the UK over the last decade, there has been a boom in projects utilising the popular phrase 'community archaeology'. These projects can take many different forms and have ranged from the public face of research and developer-funded programmes to projects run by museums, archaeological units, universities, and archaeological societies. Community archaeology also encapsulates those projects run by communities themselves or in dialogue between 'professional' and 'amateur' groups and individuals. Many of these projects are driven by a desire for archaeology to meet a range of perceived educational and social values in bringing about knowledge and awareness of the past in the present. These are often claimed as successful outputs of community projects. This paper argues that appropriate criteria and methodologies for evaluating the efficacy of these projects have yet to be designed. What is community archaeology for? Who is it for? And is it effectively meeting its targets? Focusing on the authors' experiences of directing community archaeology projects, together with the ongoing research assessing the efficacy of community archaeology projects in the UK, this paper aims to set out two possible methodologies: one of self-reflexivity, and one of ethnoarchaeological analysis for evaluating what community archaeology actually does for communities themselves.

The Polish contribution to protection of the archaeological heritage in central south Iraq,November 2003 to April 2005

Abstract

Iraq is the cradle of modern civilization, the land of ancient Mesopotamia, and thus unparalleled in its wealth of heritage sites. For years, with its strong Antiquities Law and its professional State Board of Antiquities and Heritage, Iraq protected its antiquities successfully. But since the beginning of the 1990s, many archaeological sites have been looted. Following the Second Gulf War (2003) the Polish government has attempted to assist Iraq. Since November 2003 the Polish Ministry of Culture has been delegating archaeologists for purposes of documentation, intervention and protection of the archaeological monuments located in the central southern part of Iraq, the core land of ancient Babylonia and Sumer. In close cooperation with Iraqi archaeologists, twenty-four projects valued at US$680,000 have been implemented between January 2004 and April 2005, involving aerial and ground reconnaissance and salvage recording of the most threatened archaeological sites. The Polish team has also conducted education and awareness training of the Coalition forces detachments to promote respect for heritage.     

Take the Right Decision Everybody

Abstract

The archaeological deposits in medieval towns are among the most important and distinctive heritage monuments in Norway. At the same time they are among the more challenging phenomena confronting heritage management authorities, municipal planners, and property owners/developers alike, especially in relation to building and infrastructure projects. The modern settlement has developed on top of medieval and younger deposits which means that not only are they an irreplaceable depository of historical information, but they also form a significant part of the modern town’s physical foundation.

Since 2002 the Directorate for Cultural Heritage in Norway (Riksantikvaren) has been funding systematic monitoring of archaeological deposits of the World Heritage Site Bryggen in Bergen. The monitoring programme consists of several approaches: archaeological assessment of the deposits state of preservation, biochemical investigation of preservation conditions within the deposits, hydrogeological mapping of the water table, water flow, and other given parameters.

Continuous systematic monitoring by using testable, replicable methods and measures, data, and results acquire increased quality and validity. These in turn provide the cultural heritage management with a toolbox for making correct decisions and thereby allow the government’s preservation targets to be attained. But, most important, it guarantees the preservation of the ‘underground archives’ and at the same time allows the urban centres to develop.

This paper presents the knowledge developed through monitoring the Bryggen site as a basis for an official Norwegian standard covering archaeological, biochemical, and hydrogeological deposit investigations.     

Protecting Libya's Archaeological Heritage

Libya's archaeological heritage is truly spectacular, comparatively little studied and hugely under threat. Following an extended period of isolation, improvement in Libya's relations with the rest of the world and a rise in the price of oil have stimulated a huge amount of development in the country, especially in the hydrocarbon and infrastructure sectors of the economy. With a rapidly growing population, and expanding youth unemployment, the Libyan government is attempting to develop a new way forward for its society and economy. Archaeology and heritage have not traditionally been high on Libya's agenda. The custodian of Libyan heritage, the Department of Antiquities, has been poorly supported by the state (perhaps in part relating to postcolonial Libya's ambivalent feelings towards its past) and is now badly positioned to deal with the nature and scale of development threats in the cities, the agricultural zone, and especially the desert where the greatest number of heritage assets are located. Most major development projects in these areas and elsewhere have been undertaken with little or no archaeological impact assessment, monitoring or mitigation activities, with unfortunate consequences for buried and standing archaeological remains. There are some encouraging signs of a sea change in the state's attitude to archaeology, heritage, conservation and tourism.

An ethnoarchaeological inductive model for predicting archaeological site location: A case-study of pastoral settlement patterns in the Val di Fiemme and Val di Sole (Trentino,Italian Alps)

In this paper I propose a novel integration of inductive predictive modelling and ethnoarchaeology. The case study concerns seasonal upland pastoral settlement patterns in the eastern Italian Alps. A sample of modern pastoral sites has been selected, and their relationships with environmental variables have been analyzed in order to create a model to predict the location of archaeological upland pastoral sites. The model has been tested with modern and archaeological control samples. It has proved to be useful for predicting the location of specific site categories. Ethnoarchaeological fieldwork has been carried out in the same alpine sample area, which has enhanced the interpretative potential of the proposed model, suggesting that the spatial of the analyzed sites could well be related to their dairying function. The creation of ethnoarchaeological locational models with a predictive potential may be very important not only in helping to tackle some theoretical and methodological problems in predictive modelling, but also in enhancing the importance of ethnoarchaeology in landscape archaeology projects.     

COPPER AND COPPER ALLOYS IN THE SOUTHEASTERN ALPS: AN OVERVIEW*

In recent years, several groups of archaeological metal finds from the areas around the southeastern Alps, dated between Bronze Age and Roman times, have been scientifically analysed (by ICP, AAS and/or XRF) within the framework of different projects. The data now available give a fairly good general picture of the evolution and development of metallurgy in this area and seem to indicate that the region played an important role in the exchange of objects and raw materials over many centuries. The significance of some of the metal finds, which are particularly relevant for this research, is discussed.     

A history of NASA remote sensing contributions to archaeology

During its long history of developing and deploying remote sensing instruments, NASA has provided scientific data that have benefitted a variety of scientific applications among them archaeology. Multispectral and hyperspectral instruments mounted on orbiting and sub-orbital platforms have provided new and important information for the discovery, delineation and analysis of archaeological sites worldwide. Since the early 1970s, several of the ten NASA centers have collaborated with archaeologists to refine and validate the use of active and passive remote sensing for archaeological use. The Stennis Space Center (SSC), located in Mississippi USA has been the NASA leader in archaeological research. Together with colleagues from Goddard Space Flight Center (GSFC), Marshall Space Flight Center (MSFC), and the Jet Propulsion Laboratory (JPL), SSC scientists have provided the archaeological community with useful images and sophisticated processing that have pushed the technological frontiers of archaeological research and applications. Successful projects include identifying prehistoric roads in Chaco canyon, identifying sites from the Lewis and Clark Corps of Discovery exploration, and assessing prehistoric settlement patterns in southeast Louisiana. The Scientific Data Purchase (SDP) stimulated commercial companies to collect archaeological data. At present, NASA formally solicits “space archaeology” proposals through its Earth Science Directorate and continues to assist archaeologists and cultural resource managers in doing their work more efficiently and effectively. This paper focuses on passive remote sensing and does not consider the significant contributions made by NASA active sensors. Hyperspectral data offers new opportunities for future archaeological discoveries.     

Archaeological Ethnography,Heritage Management,and Community Archaeology: A Pragmatic Approach from Crete

This article examines the introduction of archaeological ethnography as an approach to establish positioned research and bring context-specific and reflexive considerations into community archaeology projects. It considers recent critiques of heritage management in archaeology and the role of archaeologists as experts in it, contending that smaller and less prominent sites exist in different contexts and pose different problems than large-scale projects usually addressed in the literature. We describe how the ‘Three Peak Sanctuaries of Central Crete’ project, investigating prehistoric Minoan ritual sites, involves communities and stakeholders and what demands the latter pose on experts in the field. Archaeological work is always already implicated in local development projects which create and reproduce power hierarchies. It is therefore important that archaeologists maintain their critical distance from official heritage discourses, as they are materialized in development programmes, while at the same time engaging with local expectations and power struggles; they also have to critically address and position their own assumptions. We use examples from our community archaeology project to propose that these goals can be reached through archaeological ethnographic fieldwork that should precede any archaeological project to inform its methodological decisions, engage stakeholders, and collaboratively shape heritage management strategies.     

Archaeology, Development and Conflict: A Case Study from the African Continent

Apart from wars, other contexts of social conflict have recently become a setting in which archaeologists are faced with acute, sometimes armed, violence. On the African continent, a region often overlooked in discussions of “archaeology in conflict”, rapid economic development has led to several such scenes. The paper discusses a particularly poignant example from the Middle Nile valley in Sudan, where large dam projects have been met with various levels of opposition by affected populations. Local communities opposing the construction of further planned dams on the Nile are increasingly stressing ‘cultural survival’ and fear of ‘developmental genocide’ as two of their major motivations for fighting these projects. Assuming a close link between the developer and archaeological salvage missions, affected people have started to use the expulsion of salvage teams from their territory as a strategy of resistance—posing an ethical dilemma for the archaeologists who struggle to find a position in the increasingly violent controversies accompanying these contested development projects.     

Contribution to the geology of Failaka Island,Kuwait: Evidence from sedimentological and petrographic data from the NE part of the island

Kuwait–Georgian archaeological work at Failaka Island showed the need for geological study. Analysis of sediments related to drinking water-collecting cisterns was performed on a Late Islamic settlement (NE part of the island) in 2018. Field sedimentological, grain size and XRD analysis of the sediment profiles showed that the shallow (about 1 m deep) cone-shaped wells are dug in the loose, porous, cross-stratified calcareous coarse-grained quartz sandstones. Three upper layers of quartz sandstones in the profile have high infiltration rate and provide a rare yet ideal material for water retention. The fourth dense layer below, composed of very fine sand and silt fraction, tends to hinder water movement and forms a relatively impermeable water-resistant surface. Thus, the distribution patterns of clay content, grain sizes and porosity of the well-hosting sediments are favourable for freshwater infiltration and harvesting. An additional petrographic analysis was conducted on different types of rocks discovered on the archaeological site, used as building material and fragments of stone artifacts to identify their origin. It was established that archaeological building material is of local origin, whereas the source rocks for stone artifacts were imported.     

Archaeological Sites as Self-Sustained Resources for Economic Regeneration: Towards the Creation of Living Archaeological Parks on the Islands of Kythera and Antikythera

Abstract

This paper argues that less known archaeological sites on marginalized or non-touristic areas can contribute to the formation of local economies that can benefit from alternative heritage tourism and public participation in the archaeological excavation process. The discussion of a proposal for turning two archaeological sites on the Greek islands of Kythera and Anitkythera respectively (Paleokastro and Kastro) into living archaeological parks serves as an example that highlights the possibilities for the creation of self-sustainable heritage projects that need not rely on direct state funding.     

Obsidian procurement,least cost path analysis,and social interaction in the Mimbres area of southwestern New Mexico

For over 15 years chemical compositional analyses of obsidian artifacts recovered from archaeological sites in the southwestern United States have been increasingly used to address many research agendas. Despite this increasing interest in obsidian studies, few have attempted to synthesize the ever-growing amount of data generated from the numerous projects being conducted in the southwest. Here, we synthesize and present data for 923 sourced obsidian samples recovered from over 80 archaeological sites in the Mimbres area of southwestern New Mexico. We then use least cost path analysis as a means of investigating procurement patterns as well as networks of social interaction within the region.
